we need to know about weathering because if we didn't then we would us the oposite rock to what we need to use for instence if we used sandstone for a staute then it would dissolve by acid rain that's why!
Four types of weathering that can occur without water include mechanical weathering caused by temperature changes, chemical weathering due to oxygen in the air, biological weathering from plant roots and burrowing animals, and physical weathering caused by wind abrasion.
To know which of the following is a source of chemical weathering the abrasion of running water someone needs to know what the choices are. It says which of the following, but does not say what the following is. This is needed to know the answer.
if its near a tree then the roots of the tree make the sidewalk crack. i am in sixth grade and i know this! You are dumb, it would be mechanical weathering.
The physical weathering caused by the expansion of water is called frost wedging. This occurs when water seeps into cracks in rocks, freezes, and expands, causing the rock to break apart. Over time, this process can lead to the disintegration of the rock into smaller fragments.
That would be oxidation.
i need to know the answer nor answer it
I dont know :d !!
I dont know :d !!
Mechanical weathering
to presicely estimate time and effect of whatever your weathering
do not know LOL
Weathering occurs in pretty much any town. (Unless one of the towns never rains or never has winter or animals and is made completely out of mud!:D) So what you really need to know is the towns of Ohio. :)
Therew is only to types of weathering in my knowledge and they are Mechanical and Chemical (in scientific term). Mechanical is also know as physical.

Because it is good for your grade and for science.
weathering and erosion that is all i know
